@theapple: The UE40KU6100 can connect to external speakers and soundbars via HDMI ARC, Optical cable and Bluetooth therefore there's not much restricting you from a connection standpoint. If you connect the freesat box to your TV then you can choose to output audio through your soundbar via Home > Settings > Sound > Select Speaker. Samsung have a great range of soundbars and subwoofers which you may wish to consider - check them out via the link below.https://www.samsung.com/uk/audio-video/all-audio-video/?clearall
